I’ve been super-impressed with my EZ Disc super lite and EZ Hydro-gains this year. Was worried the EZ disc would be flimsy, but after a season of punishment on West Sussex’s finest highways, it’s still rock solid. A bit fiddly to fit, but it’s been great- even on hilly courses (e.g. Eastbourne Tri) and in windy conditions.
The EZ Hydo has also been rock-solid and the TriRig Kappa cages have not lost a bottle yet. I did loose a couple of screws (not thread locked, and I never bothered to check them) and a clamp arm, but customer services have been brilliant in quickly providing spares.
EZ Gains is a no-brainer. Great kit, good value and great service 👍

Really impressed with the specific fit to my Selle Italia Watt Superflow, its perfect. I went from a cheaper double bottle mount which failed over time with two 750ml bottles to the EZ Gains Hydro Mount and I'm really impressed with the quality and how sturdy it is. Also a lot easier to access/stow the bottles whilst on the move compared to the cheaper option which was under the saddle, awkward to access and fiddly. Another premium product from EZ Gains!

Contributed to my sub 5hour 70.3 and im sure it’ll aid my goals of sub 10 hour full IM!!

This product is fantastic. It combines aerodynamic improvements with practical use of tool storage. You can never have too much storage on a TT bike! This fits the bill! 👌

Unfortunately mechanicals happen and ensuring that you have spares to sort out any issues that arise is important in long distance racing. Additionally, it offers an aerodynamic way of carrying a bottle behind your saddle which EZ Gains have proved to save watts. Lots of new bikes don’t have ways of carrying anything, so this is a brilliant way to do hydration and spares

Can you check that please.

The HydroVest is one of those products that simply works. The vest itself is comfortable enough to wear as a base layer, and the 2-litre reservoir slips in easily to create a neat, aerodynamic way of carrying hydration.

I used it in a gravel race where grabbing bottles would have been definitely have resulted in me drinking less than I should. I’m not confident grabbing bottles on rough terrain and instead, I was able to hydrate little and often without taking my hands off the bike for long periods.

I also liked being able to carry more fluid than a conventional bottle setup allows. The reservoir sat neatly against my back, felt secure throughout the race and didn’t create much of an “camel hump” appearance under my jersey.

For long rides, mountain bike or gravel racing or any event where easy access to hydration matters, it’s a really practical bit of kit.

As a professional triathlete, I'm always looking for those extra 1% gains in both training and equipment. I recently did some testing with the Hydro Glide in the pool to see what impact it would have on my swimming.

Cooling Effect - One of the biggest challenges I face is overheating when swimming in a wetsuit indoors, which usually limits how long I can comfortably stay in the water. With the Hydro Glide's ice packs, I was able to spend significantly longer swimming in my wetsuit before feeling too hot. This will be a really valuable tool for my wetsuit-specific training sessions.

Hydrodynamic Performance- I also wanted to see if the Hydro Glide had any effect on swimming performance. To test this, I completed a controlled comparison, swimming the same sets with and without the Hydro Glide. Interestingly, the swims completed with the Hydro Glide were consistently faster while requiring what felt like the same level of effort (see attached image).

My original Fizik Holder broke right before my IRONMAN. The Hydro Gains is much stronger and gives me aerodynamic advantages.

The best part: The customer service sent out the package with priority, so that there was enough time for me to test everything.

Thank you very much!

I'm a competitive age-group triathlete — 3× GB Age Group World Championships qualifier, sub-1hr Ironman swimmer. I don't buy swim gadgets on faith — I test them.
I ran the EZ Hydro-Glide across three sessions: two pool tests (400m time trial + 6×100m intervals) and one open water session. Every session was a solo effort — no feet in front, no drafting advantage.
The numbers:

Pool 400m TT: 5:30 with device vs. 5:36 PB without — 6 seconds faster
Pool 100m intervals: consistent ~5 sec/100m improvement across all reps
Open water 550m loop: ~5 sec/100m improvement vs. pre-device baseline

The consistency is what stands out. This isn't one lucky swim — it's the same result across different formats, distances, and environments (pool and open water, with and without wetsuit).
The mechanism makes sense when you think it through. The device puts your head in an optimal position and breaks the water more hydrodynamically. Better head position cascades through the whole body — it lifts your torso, which raises your hips, which reduces drag at the hip and kick zone. The whole body sits higher and flatter in the water, and you're faster as a result.
Caveats: This is personal testing, not a controlled study. Sample size is three sessions. I'd want more data before drawing firm conclusions about long-term adaptation. But as an initial result? It's compelling enough that I'll be wearing it at my next start line.
At 5 sec/100m over a 3.8km Ironman swim, that's roughly 3 minutes off my swim split. My current Ironman swim PB is 57:14 — that puts a sub-54 in range. In a sport where every minute saved in the water means fresher legs on the bike and run, that's not a marginal gain.

Perfect fit with my ISM PN 3.0 saddle and very secure. These guys ship fast, ordered a week out from a 70.3 and surprisingly showed up 2 days before. Not much practice with it but worked out great. Love the adjustability.

Aero Chainring Guard Tape

Works well, and fitted my wheels perfectly.

The instructions (as of May 2026) are very poor but EZ Gains email support was very quick and helpful (over a bank holiday weekend!) and I understand the instructions are being re-written.

It's actually quite simple to fit, and so far it's been secure with no rattles.

Sadly not (yet) homologated for UCI-regulated track events, but OK for non-UCI events.

Great to support a pioneering UK business that offers genuinely excellent customer service.

Great addition to my tt bike setup. Very solid mount with great bottle retention. Stable during rides and keeps hydration accessible behind the saddle. The Hydro Gains fits neatly between the aerobars, keeps hydration accessible clean designs , easy access bottle and looks very aero. Stable on rides. Excellent product. Great upgrade for my race 👍❤️🔥🔥

Well designed and built. It gives you endless adjustability on angle and fore/aft to get the bottle in exactly the right place for you. I like the fact its so easy to fit and has been great to use on training rides this year. I look forward to using it for lots of long course racing this year!

I had a couple of issues when making a recent purchase. The phone was answered promptly, helpful information was given and they managed to sort out what could have been complicated issues re my purchase and billing address without fuss.. I even received a text message at 7am to say it would be sorted as soon as Chris? got into the office. Unfortunately service and responses like this have become rare. Company’s forget that their USP is not just the product but dealing with customer related issues. EZ gets 10 out of 10 here. Keep up the good work.
